# The funny quoting in `LLVMLIBS' avoids a warning from Automake:
#   ...: linker flags such as `--libs' belong in `clang_delta_LDFLAGS'
# The warning comes about because Automake doesn't understand $(shell).
# Avoid the warning by making `--ldflags' and `--libs' not look like
# linker options.
#
# Also: Only LLVM post-3.4 supports `llvm-config --system-libs'.  There's no
# harm in invoking it for LLVM 3.4 and below, but we want to avoid the usage
# message in those cases; hence the redirection.

# Try to do the "right thing" by putting these in `clang_delta_LDADD' instead
# of `clang_delta_LDFLAGS'.  This leads to the funny escape in `LLVMLIBS',
# above, and the need to define `clang_delta_DEPENDENCIES', below.
#
# The output of `llvm-config --ldflags' often contains library directives that
# must come *after* all the LLVM/Clang libraries on the link line: e.g.,
# "-lpthread -lffi -ldl -lm".  The easiest way to get these into the right
# place is to add `LLVMLDFLAGS' to `clang_delta_LDADD' --- *not* to
# `clang_delta_LDFLAGS'.  Automake puts LDFLAGS early in the link line.
#
# Newer LLVM's (post-3.4) support `llvm-config --system-libs', which will
# possibly help us to straighten this out in the future.
